National audienceAbstract: This paper addresses the problem of source localization with only one sensor. A new metric called Hausdorff Distance (HD) for an optimal matching, is used for TDOAs best matching between simulations (TDOAs) and real data (TDOAr). To obtain the simulated impulse response, we drive an acoustic ray path propagation method. So we compare these simulated data with TDOA estimated after matched filtering considering a known transmitted signal. Two derivated techniques from HD are presented to find correct position, in range and depth, 1) the Maximum Hausdorff distance and 2) the Median Hausdorff distance. Results in terms of the localization, accuracy are shown in a real tank experiment.Cet article traite du problème de ...
